Abstract

The RISING setup at the GSI-FRS facility was used to investigate the isomer and beta decays in N~Z~50 Cd, Ag and Pd isotopes. A preliminary analysis of the data has revealed new results on the Tz=1, ⁹⁴Pd, ⁹⁶Ag and ⁹⁸Cd isotopes. In ⁹⁴Pd a new high-spin isomer was observed, whilst in ⁹⁶Ag 3 new isomeric states were identified, including core-excited states. In ⁹⁸Cd a new high-energy isomeric γ-ray transition is observed, thus enabling us to confirm the previous spin assignment for the core-excited 12⁺ isomer.
